What happen to the potential energy of an object as it falls?
It is tranferred/converted into kinetic energy (DECREASES)
What will happen to your kinetic energy if you double its objects velocity?
8
What will happen If the energy content of an object continually increases?
What type of energy? Thermal, kinetic, gravitational, electrical?
A rotating fan blade has kinetic energy when rotating with constant angular velocity when the angular velocity is reduced to one third what will happen to the kinetic energy?
It will decrease by a factor 9.
What will happen to the kinetic energy of gas molecules trapped in a rigid container if the temperature is increased?
increased
What will happen to the potential and kinetic energy as the ball falls?
Gravitational potential energy increases; kinetic energy increases.
What happen to the potential energy of an object as it falls?
It is tranferred/converted into kinetic energy (DECREASES)
Which state of energy is when something is ABOUT to happen?
Potential energy is energy that is not kinetic or moving.
When she releases the ball what is will happen?
the ball will have kinetic energy and potential energy.
How does kinetic energy happen?
if a body posses motion
What will happen to the kinetic energy of the object as it falls?
Increase.
What will happen to the kinetic energy of the body if the mass of the body is halved and velocity remains the same?
Kinetic energy will also be halved. Because kinetic energy is equal to 1/2 mv2
What will happen to the kinetic energy for an object if its mass is double but the velocity remains at the same?
Kinetic Energy = (1/2)*(mass)*(velocity)2 If you double the mass, then the kinetic energy will double If you double the velocity, the kinetic energy will increase by a factor of 4
Is Kinetic energy waiting to happen true or false?
True
What happen to kinetic energy of particles of liquids when its temperature is raised?
Since temperature is a measure of kinetic energy, so as kinetic energy increases, temperature must also increase or vice verse
What will happen to the kinetic energy of a body if m equals 2m?
Kinetic energy = 1/2 (mv)2 if m increase by 2m, then Kinetic increases by 2
What should happen to the temperature if the kinetic energy is reduced?
It will decrease
